During some recent "equality and diversity" training, I learned that it is increasingly common for Muslim employees in the UK to object to working with or assisting blind people who use guide dogs -- dogs being traditionally considered unclean in Islam. Although our teacher didn't say it in so many words, this is an excellent example of why a blanket policy of "religious tolerance" can never work: Sometimes there is no way to respect one person's beliefs without interfering with another person's rights. I'm happy to say that British law is firmly on the side of the blind in these cases.
One of my first reactions to hearing about this (besides an odd fantasy about Christopher Hitchens being a member of our training group) was to wonder how blind Muslims cope with such a prohibition. It turns out that just a couple of days ago, The Age ran a story about two blind Muslim women who have defied the taboo and welcomed canine helpers while keeping their faith intact. I hope many more blind Muslims will find new freedom by following their example.
